[OpenLayers-Users] Layer from GML loading only for the first time

[Arnd Wippermann]

Hi,

So far I rembember, there is a function setUrl to change the url for a gml
layer after layer creation. And also you link to the same as previous, the
new data will displayed. 

So you don't need to add-remove-add your layer to display new data from a
GML vectorlayer.

yourLayer.setUrl("http://...."); should do the trick.

Arnd

Hi,

Thanks for your reply.
So how to do the following:

1) change the cache
settings on your webserver for the XML1 subdir (tell the browser to never
cache the file)?

2) append a random number to the url?
Pls tell in details.

Regards.
